It's available for all religions but muslim, catholic, orthodox, judaism_group (no female marshals for these), hubal, and gurzil (female marshals always allowed without restrictions for these latter two) unless you guys think there should be tighter restrictions. I've added 2 more steps (Allowed now permits females with martial education and 20+ martial to serve, Accepted permits females with martial education and 12+ martial to serve, Approved permits any female to serve.) Going up the scale has the same requirements for each step (very high martial brilliant strategist female monarch), going down scale has no requirements. There are opinion consequences for the law changes. Males always approve of more restrictions on female marshals/commanders and disapprove of fewer restrictions, females are more split on the matter, depending on law level and traits.
